Answer:

12583.2 J or 12.5832 KJ

Step-by-step explanation:

Work done can be expressed as force multiplied by displacement, or

W = Fs

In this case, we can calculate the force by using F = mg.

m is the mass, 214 kg, and g is gravitational acceleration, which is 9.8 m/s/s.

So, we Calculate 214 * 9.8 to get 2097.2

The displacement is 6m.

So, by doing W = Fs, we get

2097.2 * 6 = 12583.2 Joules
